" Heaters, of which the `following is a specifcation.

The object of this invention is to provide a simple, inexpensive andeflicient device whereby the air rising from a heater may bedisseminated and caused to more rapidly circulate through a room than isordinarily the case so that the room will be more thoroughly heated andits temperature quickly raised to the desired degree.

The preferred embodiment of the invention is illustrated in theaccompanying drawings and consists in certain novel features which willbe lirst fully described and then more particularly pointed Vout in theappended claims. Y

In the drawings:

Figure 1 is a perspective View of my device in operative position upon acylindrical stove;

. Fig. 9. is a trans-verse section;

Fig. 3 is a horizontal section on the line 3-3 of Fig. 2.

The device constituting my invention is` intended more particularly foruse in connection with stoves having cylindrical bodies, as indicated at1, but it may, of course, be applied to heating units of any form orcharacter.v In carrying out my invention, I employ a base ring 2 whichmay be made of various diameters and in any particular in stance will beof the proper diameter and form to iit closely around the top end of thestove and thereby support the device in position thereon. Rising fromthe base ring 2 are guards or posts 3 of stout wire or similar materialand supported by the upper ends of the said guards is a disk or hood 4Lprovided at its center with a collar or sleeve 5 to receive the lowerend 6 of a motor casing "7. The extension 6 of the motor casing formsthe hub or bearing for a fan shaft 8, to the lower end of which issecured a plurality of radial fan blades 9. In the preferredform of theinvention, which is illustrated in the accompanying drawings, the fan isdriven by an electric motor contained within the casing 7 and current towhich is supplied by a conductor l0 which may run from any convenientelectric lamp socket. It is to be un derstood, however, that the fan maybe driven bya pulley and belt connection with a distant motor if sodesired or preferred, but in any event my invention contemplates theprovision of a positively driven fan located and supported over, in orupon va heater.

The use of the device is thought to be obvious from the foregoingdescription, taken in connection with the accompanying drawings. Theheat rising from the stove will be arrested by the hood or disk 4 sothat it cannot pass directly upward and accumulate in theupper portionof a room as is now generally the case. The disk or hood will obvio-usly serve to deiiect the heated currents, but if they were merelyturned aside by the hood they would simply pass up around the edge ofthe same so that eli'ective lateral dissipation would not be attained.By provid ing a fan, however, which is positively rotated between thehood and the top of the stove, the hea-ted currents are driven laterallyfrom the stove and will be caused to iiow horizontally or obliquely toan appreciable distance in all directions, the result being that thetemperature in the room is more quickly raised to the desired degree andis made more uniform than has heretofore been possible. The fan isrotated in the direction indicated by the arrow a in Fig. 2 so that whenthe blade is set at an angle the lower face of the blade will meet theheated currents rising from the stove and will, consequently, throw themoutwardly instead of throwing them upwardly against the hood or disk aswould #be the case if the fan were rotated in the opposite direction. Ifso desired, the blades may be set so that their outer end edges will bevertical in which event the direction of rotation will not be soimportant inasmuch as rotation in either direction will forcibly propelthe currents laterally from the space between the stove and the hood ordeflecting disk. The base ring should be of such diameter than it williit the top of the heater closely and thereby furnish a iirm support forthe hood but may be instantly withdrawn `from the heater when desired.The guards or supports extending between the base ring and the hoodeffectually prevent persons coming in contact with and being injured bythe fan blades, while at the same time they effectually support the hoodwithout obstructing 4the escape of the heated llO currents under theinfluence of the fan. The device may be applied to radiators or otherforms of heating unitsand may be support; ed on a separate standextending over the heating unit While the motor may be at the lower endof the fan shaft but, for the greatest, efeency, the, fan, shaft shouldybe approximately Vertical.

Having thus described my invention, what isclaiined as new is:

l. A'deyiee forthe purposeset forth com,- prsng basememben 'afdptedft'otn the top' ofA a` heater, rising from said member, a,y hod supportedthe'upperl,

ends ofsaid guards, and a positively driven fan arranged between thehood and the base member.

2. A device for the purpose set forth Comprising a base member adaptedto engage the top of a heater, guards rising from said member, a hoodsupported by said guards, a bearing at` the center. of said hood, and apositively driven fanjournaled in said bearing and arranged to operatebetween the hoodand the top of the heater.

In' testimony whereof I aiiX my signature.
